One: the application of serial server in photovoltaic power station

Summary:

Photovoltaic industry is also known as the solar industry, because of the remote location of photovoltaic power station, geographical environment, natural environment, and wide distribution, large number of equipment, maintenance task is very heavy, in order to improve efficiency, reduce maintenance task, intelligent monitoring and management system of photovoltaic power station is particularly important. Photovoltaic power station intelligent monitoring and management system is the photovoltaic power station battery array, inverter, confluence box, weather instrument, solar tracking controller and other devices are connected, monitoring host through serial port server and industrial Ethernet switch to monitor the data of each device, convenient for users to view the relevant data and management.

Introduction:

Serial port server converts serial port data into Ethernet data format and transmits it in Ethernet network, which solves the problem of data communication between devices with different protocols.

The 485 bus processing Ethernet switch is used to connect the photovoltaic panel to form a self-healing ring structure, which can ensure that the communication of other sites is not affected when the cable is accidentally disconnected or other equipment fails. The data of the photovoltaic panel area monitoring point is converted to Ethernet through the serial port server and collected to the control room or the monitoring center host, which can effectively monitor the health of each device at the lower end in real time.
